Ria is a big fan of "Uyu-sama" immediately after Uyu suddenly announced that he was going on hiatus, a new student, Yutaka, arrives...and it turns out to be Uyu himself! Ria is shocked to see that he is a different person from the one she saw in the video, but she can't help but hate him because she is in love with him for the first time. Seeing her, Uyu somehow recruits Ria to be his manager...?
